DEVICE FOR HEATING AND COOLING MATTRESSES.

To all whom it may concern: 7

Be it known that I, MARK S. MARUDA, a citizen of Russia, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Im rovements in Devices for Heating and ooling Mattresses, of which the following is a specification.

The present invention relates to new and useful improvements in beds, particularly devices for heating and cooling bed-mattresses.

One object of the invention is the provision of a heating or cooling device for beds including a plurality'of heating or cooling pipes which are so connected with the heat and water service of a house or apartment that any desired degree of heat may be supplied and maintained in a bed.

Another object of the invention is the provision of a device of this character which can be easily and cheaply installed in any bed.

A still further object of the present invention is to provide and simplify devices of this kind or character, rendering them comparatively simple and inexpensive to manufacture, reliable and efiicient in use, and readily operated.

It is to be understood in this connection, that various minor changes in the specific details of construction can be resorted to within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

With the above and other objects in view, the present invention resides in the novel features of construction, combinations, and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which- Figure 1 is a side view of a bed equipped with a device constructed according to the present. invention, partly in section along line 11 of Fig. 3.

Fig. 2 is a side view of a bedstead showing the inletand outlet control for the heat or water supply.

Fig. 3 is a top plan view of a bed-mattress equipped with the device according to the present invention, and

Fi 4 is a top plan view of a pipe carrying p ate.

The bed 10 equipped with the heating and cooling device according to the present invention comprises the customary head board Specification of Letters Patent, Patented SGEH]. 27, 1921. Application filed September 1, 1920. Serial No. 407,334. I

11, foot board 12, bed bottom 13, sides 14, and feet 15 on rollers 1 6. Upon the bottom 13a plate 17 is supportedby means of its supporting flanges 18 which plate is pro- "vided with upstanding marginal flanges 19 along its outer edges. Upon this plate a plurality of bed springs 20 of the customary spiral type are supported with their lower, narrower ends secured to said plate, while their upper and wider ends are resting against a plate 21 carrying the mattress 22 of any desired make or type. The springs 20 as shown, are arranged in a plurality of rows and a pipe 23 adapted to be connected by a suitable connection 24 to the heat or water supply pipe 25 of the heating or water main of a house guided underneath the floor 26 of a room 27. The supply of heat or water through the connection 24 is controlled by a hand operated valve 28. From the connection 24, the pipe 23 is guided parallel to the head-board 11 while resting upon the plate 17, and is then bent to form a knee 29 whereupon it is guided in a plurality of Bands 31 and 32 are provided to secure the I pipe at its bends to the part 23 thereof, while other similar bands 33 secure the opposite bends 34 of the pipe to the flange of the plate 17. From its last bend 35, the pipe is guided parallel to the side 14 and connected by means of the connections 36 to an exhaust pipe 37 and the exhaust is controlled by a control valve 38.

From the foregoing description it will be clear, that either steam or water may be supplied to the pipe 23 by the operation of the valve 28 and by circulating through the convolutions of the pipe 23 a desired amount of steam or water, the bed and the mattress may be heated or cooled to any desired de gree required or necessary in the treatment of a patient resting on the mattress.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States, is-

1. Device of the character described comprising in combination with a bedstead and mattress therefor, a flanged support plate, means for supporting said plate on the bed stead-bottom, a plurality of coiled springs supported and fastened with their lower ends on said plate, a pipe conduit consisting of a plurality of convolutions secured to said plate between the single rows of springs,

connections for said pipe conduit with a source of Water and steam, and valves for controlling the supply and exhaust of said Water and steam.

2. Device of the character described com,- prising in combination with a bed-stead, and mattress, a flanged plate, means for supporting said plate upon the bed bottom, a plurality of spiral springs resting and secured with their lower and smaller ends on said plate, a plate to which the upper, Wider ends of said spiral springs are secured, a mattress on said last named plate, a pipe-conduit consisting of a plurality of convolutions guided between the single rows of said springs and 15 resting uponsald plate, bands securingv sa1d pipe conduit to'the flanges of said plate,

connections at the ends of said pipe conduit ,MARK s, MARUDA.
